ERW tube mill & pipe mill
At first, the coil is loaded at the uncoiler, then but-welding the ends of coil, delivering to accumulator. After accumulator, the strip is pulled from accumulator contentiously by fixed speed, is formed to opened-pipe at forming machine, then welded by High frequency welder, deburred, cooled, shaped and sized as round pipe and rectangular&square pipe at the sizing area. Then the sized pipe is straightened after Turkey-head device and then cutt to fixed length by flying saw. At last, the fixed pipe is delivered from run-out table and inspected at the table.
ERW Steel Tube Field of use:
With steel tube, steel pipe thermal equipment, industrial machinery and steel, petroleum, geological drilling steel, container steel, chemical industry with steel pipes, steel pipes for special purposes, other.
ERW steel pipe is rolled into a tube-shaped steel sheet to the seam or spiral seam welded, in the manufacturing method, is divided into low pressure liquid delivery welded steel pipe, spiral seam welded steel pipe, straight welded steel pipe, welded pipe. Seamless steel pipe can be used in various industries liquid pressure pipelines and gas pipelines. Welded pipes can be used for water pipes, gas pipes, heating pipes, electrical pipes.
Tube mill production process:
According to different customer, the machinery consist by different process, but our company having the standard production process as blew, this is for your reference, suppose your company have special requirement, we could discuss and make your special design.
Uncoiler→ Shear&welding machine→ Accumulator (Cage) →Forming machine→ HF welding→ Sizing machine→ Flying saw (Cold saw) → Run out table→hydro testing→end facing
for API standard we can equiped online testing equipments, like Hydro testing equipment, End facing equipment, UT testing, ECT testing etc.
